thanks pradeep

so to clarify. your sayin a person can hack into my network, i.e. they can take advantage of my connection, mainly those nearby me. Is that what u mean by hack in network?

But they can't use my IP address or the facet that I have picked up someone's connection to hack into my laptop system and view my personal details?

I have occasionally used websites on my laptop where i have typed in my personal details such as my name and address, no one can see that information can they? by hacking into my network?

thanks
